condor_restart restarts a set of HTCondor daemons on a set
of machines.
The daemons will be put into a consistent state,
killed, and then invoked anew.

If, for example, the condor_master needs to be restarted again with
a fresh state, this is the command that should be used to do so.
If the DAEMON_LIST variable in the configuration file has
been changed, this command is used to restart the condor_master
in order to see this change.
The condor_reconfigure command cannot be used in the case where the
DAEMON_LIST expression changes.

The command
condor_restart with no arguments or with the
-daemon master option
will safely shut down all running jobs and all submitted
jobs from the machine(s) being restarted, then shut down
all the child daemons of the condor_master,
and then restart the condor_master.
This, in turn, will allow the condor_master to start up
other daemons as specified in the DAEMON_LIST configuration
file entry.

For security reasons of authentication and authorization,
this command requires ADMINISTRATOR level of access.

To restart a machine within a pool
other than the local pool, use the -pool option.
The argument is the name of the central manager for the pool.
Note that one or more machines within the pool must be
specified as the targets for the command.
This command restarts
the single machine named cae17 within the
pool of machines that has condor.cae.wisc.edu as
its central manager:
